Why Kids Should Learn to Code

Why Kids Should Learn to Code

Most Americans love their laptops, tablets, and smart phones, but according to a recent study by the  Organisation for Economic Co-operation and Development (OECD)  few Americans know much about how their favorite technologies work. When it comes to using...

What is a microcontroller?

What is a microcontroller?

All of our MakeCrate electronics subscription kits use an Arduino microcontroller as well as a variety of digital and analog sensors and displays to create nightlights, calculators, room alarms, and more. Because the microcontroller is a fundamental part of every...

Circuit Basics:  Electricity Flow

Circuit Basics: Electricity Flow

Transcript: Let's take a look at the steps required to build a circuit that allows electricity to flow correctly. In each of the projects that we build at MakeCrate, we start by connecting a wire to the 5V connection on our Arduino to our breadboard, and then...

While loops

While loops

A common coding structure is the while loop. This is used when you need an action or event to occur for the entire time a condition is met or another action is occurring, but not at other times.  To understand this in more depth, watch this video and learn about while...

If-Then Statements

If-Then Statements

If you are writing some code and need an event to occur only when some other event has occurred or a specific condition has been met, an if-then statement might come in handy.  Explore how these work in the Arduino IDE:  

For Loops

For Loops

There are a few programming structures that are common across languages.  For-loops are one of those.  For  loops are commonly used when an action needs to be performed a specific number of times. Take a look at this video to begin to learn to build a working for-loop...

How does an ultrasonic sensor work?

How does an ultrasonic sensor work?

Learn the science and math behind an ultrasonic sensor. Transcript:  An ultrasonic sensor can be used to calculate how far away an object is. These sensors can be used to determine things like how far your car is from a wall, or whether or not your water bottle is in...

How does a photoresistor work?

How does a photoresistor work?

Learn about the properties of semiconductors that allow photoresistors to work. Transcript: Let’s take a look at how a photoresistor works. A resistor is an electronic component that reduces the amount of current flowing through a circuit.  A variable resistor is one...

How does a buzzer work?

How does a buzzer work?

  Curious what is happening inside a buzzer? Check out this video. Transcript: Buzzers can be both fun and useful in electric circuits.We’ll use them a lot in MakeCrate projects, so let’s take a look at what is going on inside a buzzer to produce sound. The buzzer...
